The best double units automatically cleaning welding dust
allayer & suppressor
Product introduction
1. Mobile intelligent welding fume extractor has two directional
and two rotary polyurethane casters with brake device for easy
moving and stationing. It is suitable for the purification of fume
and dust generated in all kinds of welding, grinding and other
places as well as for collecting rare metal particles and precious
material.
2. The filter elment of the welding fume extractor is made of
imported PTFE membrane filter material of high filtration
precision, and the filtration precision reaches 0.1 μm. In
accordance with the extractor work intensity and the amount of
dust, the usage life of the filter is different.The corresponding
indicator on the control panel will light up to indicate different
conditions and a power phase sequence indicator, phase absence and
short-circuit protection are set inside. It’s equipped with
automatic shutdown mechanism when the temperature is too high
(optional).
3. The fume comes from the processing will be sucked into the
extractor through the hood, first the fume passes the 1st layer spark intercept steel mesh which will separate and intercept
the spark initially. And the fume enters into second layer namely
filter preventer plate to avoid residual sparks enter into main
filter layer directly through ramifying the fume. At last the fume
enters the third layer namely the main filter cartridge for
ultimate purification.The filtration efficiency can reach 99.9%.
4. On the control panel, it includes:
- Power switch
- Power indicating light
- PLC implementation of filter automatically cleaning
- Fan rotation direction monitor (Inside the control
box)
Working principle
Separation: Dust laden fume are sucked into the extractor by the suction
force induced by fan’s working, with deflector fume’s flowing speed
is slowed, big practical and sparks are cooled, separated and then
settle into dust collector. Fine fume and dust enter into filter
compartment to be filtered by the filter cartridge. The filter
cartridge is coated with PTFE film which is covered with uniform
pores, it has good air permeability, and dusts are filtered out on
its surface. Purified air enters into the filter cartridge’s
interior and then discharged into workshop directly or out of the
workshop through pipe line.
Cleaning: When dusts accumulate continuously on filter cartridge’s surface,
the pressure difference between its interior and exterior will
increase steadily, when the pressure difference reach pre-set
value(1500Pa), the pulse valve will open, dry, oil-free compressed
air rush into the reverse blow cleaning system. The system rotate
and high pressure air stream jet at the interior of filter
cartridge, blow off dusts accumulated on the filter cartridge’s
surface, dusts fall into dust collector under gravity, thus the
whole cartridge’s surface is cleaned.
This extractor can be automatically cleaned and manually cleaned,
automatically cleaning is as following:
1. When air pressure difference reach 1500Pa between the interior
and exterior of the filter cartridge, the system will implement
interval rotation pulse blow cleaning.
2. When the fan stops working, the system will implement rotation
pulse blow cleaning for three times.
Main features
1. CE certification and EMC test report is approvable.
2. Application for large fume occasion, the force of sucking is
large.
3. Large air flow is adjustable through the air flow valve on the
suction hood.
4. Automatically cleaning, maintenance easy, filter cartridge
service is long.
5. Schneider,CHNT electrics, Siemens PLC and montoring screen,
USA gas-pressure switch, Japan Toray filtering material, AKZO
Nobel spraying powder etc.
